torque on the foundation is clearly an engineering problem that will have a straightforward solution
the engineering solution always has associated costs and efficiencies
higher toppling torque will cause higher foundation/support costs
modern wind turbines have settled on the 3 blade propeller...with aerodynamic lift..
although the old wooden windmills in europe were OK for grinding flour
they would not scale up economically to the height / power of modern propeller windmills.
no matter how good the engineers were..
as W has stated , there may be a unique niche market for the Aesop turbine.
